I don't agree completely with some of the YouTube guy's perspective, but it is good to see some aspects of the actual job becoming more available for prospective candidates to see.
You shouldn't have to pack 4 days worth of ramen noodles and cans of tuna in order to perform your job. I rarely bring anything, but I can afford to buy food. Unfortunately you are at the mercy of the schedule, the delays you're trying to minimize, and finally the food options available at the airport, which in Charlotte are nothing more than abysmal.
If you're young enough that you think Burger King is an adequate food option, you'll do well in this environment.
Let's face it, if the HR recruiters and PSA marketing materials were honest about the pay, and daily challenges involved with the job, they'd get a lot fewer pilots who are frustrated enough to make YouTube videos about their experience.
Of course, if they were honest about everything, they'd get fewer pilots to come here, which would be counter to their goal.
